Ferrets
Best escape proof ferret cages
Ferrets do not break out. They find the one gap you did not measure, and on most cages it is the door.
Buy the MidWest Critter Nation Double Unit (162): its double-locking door latches are the only hardware in this group a ferret cannot work open by pushing, its half-inch bar spacing is the tightest here, and its full-width doors close against a frame rather than onto a gap. The budget pick is the Critter Nation Single Unit (161) — identical hardware and bar spacing in one storey, and the cheapest genuinely escape-resistant ferret cage we assess. The Ferret Nation 182 is the alternative if you find it cheaper, with one caveat we explain below about its published bar spacing. The Prevue 485 Feisty Ferret is the pick if you want a smaller footprint and are prepared to add a clip to the door. Prices are live with an as-of date under each button.

Escape-proofing a ferret cage sets out the method: check the latch, check the pan gap, check the shelf seam, check the corner. What that page has never had is a list of cages where those four things are right from the factory. This is it.
The reason the method page came first is that a ferret escape is almost never about the bars. It is about a gap between two parts that were made separately, and the usual culprit is the door.
The four places a ferret gets out
- 1.The door latch. A single sliding bolt can be worked loose by a ferret pushing rhythmically against the door for twenty minutes. A double-locking latch, or two independent catches, cannot. This is the specification that decides this page.
- 2.The pan-to-frame gap. The slide-out base tray is a separate part, and the slot it slides into is a gap by design. A ferret that can get its head in will follow it, which is why we note how each pan seats.
- 3.The shelf seam. On a cage with a removable shelf, the join between the shelf edge and the frame is another manufactured gap. Solid shelves that sit on a lip are better than wire shelves that clip on.
- 4.Bar spacing, at the corners. Mid-panel the bars are fine on every cage here. At the corners, where two panels meet, the spacing is often a little wider — and a ferret is a cylinder that follows its head.
- 5.Not the roof. Ferrets climb but they are not jumpers in the way people expect; how high can a ferret jump has the figures. A secure lid matters, and it is rarely where the escape happens.

Every figure is the manufacturer's own as published on the listings cited on the cards below. We have not measured a latch, a gap or a bar spacing ourselves, and no veterinary or welfare body publishes a figure for any of them - VCA publishes a cage size and nothing about hardware.
The Ferret Nation row needs its caveat stated plainly rather than buried, and it is a documentation problem rather than a defect. MidWest publishes no bar spacing for the Ferret Nation in its own specification sheet, and the retail listing states it twice, differently. Our Ferret Nation 182 review records that finding in full. The cage appears to be built like its Critter Nation sibling; what we cannot do is cite a figure for it, so we have not.
Who each of these is for
- Two or more ferrets, and a confirmed escape artist: the Critter Nation 162. Double-locking doors, the tightest published bar spacing here, and two storeys of solid shelf.
- One or two ferrets, cheapest route to the same hardware: the Critter Nation 161. The same doors and bars in a single storey, and it takes the second unit later.
- A bargain on the 182: take it, and measure the corner bar spacing against your ferret before you leave it unsupervised, because the published figure is not reliable.
- A small room, with DIY tolerance: the Prevue 485. Smaller footprint, single door catches, and a carabiner on each door solves the hardware gap for a few dollars. Best ferret cages has the fuller assessment.
- Nobody: any cage with bars over an inch apart, a plastic-molded door, or a lid that rests rather than latches. None appears on this page.
Our pick · Ferrets of any age, and kits especially
MidWest Critter Nation Double Unit (162)
The half-inch bar spacing is the whole argument: it is the same cage as the Ferret Nation with a gap a ferret kit cannot get its head through.
- Dimensions
- 36 x 24 x 63 in including the rolling stand
- Continuous floor
- 36 x 24 = 864 sq in (6 sq ft) per level, two levels
- Bar spacing
- 1/2 in horizontal
- Material
- Powder-coated steel with deep removable plastic pans
- Levels and ramps
- Two levels with a locking swing-up ramp and full-width doors
What it gets right
- 1/2 in bar spacing holds a kit that 1 in spacing does not
- 6 sq ft of usable floor per level, comfortably over our per-level bar
- Full-width doors mean you can reach every corner, which matters weekly
- Deep pans contain litter rather than spreading it
What it gets wrong
- Horizontal half-inch bars give less climbing purchase than wider spacing
- Heavy and awkward to assemble alone
- The stand's casters roll on hard floors more than you want them to
Who should buy something else
Not necessary if your ferrets are adults and you have measured their head width against 1 in. The Ferret Nation costs less and climbs better; the half-inch is insurance you may not need.

Number 2 · A single ferret, or a first half of a double
MidWest Critter Nation Single Unit (161)
The same 6 sq ft floor and the same half-inch bars in one level, which is the right buy only if you are certain you will add the second unit.
- Dimensions
- 36 x 24 x 25.625 in for the cage section
- Continuous floor
- 36 x 24 = 864 sq in (6 sq ft), one level
- Bar spacing
- 1/2 in horizontal
- Material
- Powder-coated steel with a deep removable plastic pan
- Levels and ramps
- One level, with a shelf; a second unit stacks on top later
What it gets right
- Identical 1/2 in bar spacing safety
- 6 sq ft of usable floor
- Cheaper entry point, and the 162 upper unit fits it later
What it gets wrong
- One level gives a ferret much less vertical variety than two
- Buying the single then upgrading costs more than buying the double outright
Who should buy something else
Wrong for two or more ferrets. One level of 6 sq ft is enough floor and nowhere near enough structure for a pair that will spend their waking hours in it.

Number 3 · Adult ferrets that climb
MidWest Ferret Nation Double Unit (182)
Slightly more floor per level than the Critter Nation and a one-inch bar gap, which is fine for a grown ferret and the reason kits escape.
- Dimensions
- 36 x 25 x 62.5 in including the rolling stand
- Continuous floor
- 36 x 25 = 900 sq in (6.25 sq ft) per level, two levels
- Bar spacing
- 1 in
- Material
- Powder-coated steel with deep removable plastic pans
- Levels and ramps
- Two levels with locking swing-up ramps and ramp covers
What it gets right
- 6.25 sq ft per level, marginally more than the Critter Nation
- 1 in bars give much better climbing purchase
- Same full-width doors, deep pans and locking ramps
- Usually cheaper than the equivalent Critter Nation
What it gets wrong
- 1 in spacing is the single reason ferret kits get out of this cage
- No way to retrofit narrower spacing; the fix is a different cage or wire panels
Who should buy something else
Never for kits, and not for a small jill who can flatten her head through a one-inch gap. Measure the animal, not the marketing, and buy the Critter Nation if there is any doubt.

Number 4 · A smaller room and a single adult ferret
Prevue Pet Products Feisty Ferret Home 485
A cheaper multi-level cage whose 4.3 sq ft per level and 7/8 in bars both land below the standards we apply, which is the honest reason it is last here.
- Dimensions
- 31 x 20 x 54 in with the stand, 41.5 in high without it
- Continuous floor
- 31 x 20 = 620 sq in (4.3 sq ft) per level
- Bar spacing
- 7/8 in
- Material
- Powder-coated wire with removable platforms, grille and debris tray
- Included fittings
- Ramps, shelves and a hammock supplied
What it gets right
- Fits a 31 in footprint where the MidWest cages need 36 in
- Hammock, ramps and shelves included
- Removable grille and tray make cleaning straightforward
What it gets wrong
- 620 sq in per level is 28 percent less than the Critter Nation
- 7/8 in bar spacing is close enough to 1 in to carry the same kit risk
- Lighter gauge wire than the MidWest and Savic cages
Who should buy something else
Not for kits, not for two ferrets, and not if you can fit a 36 in cage. It solves a space problem and does nothing else better.

What to do on the day it arrives
Fifteen minutes, before the ferret goes in. Push every door from the inside with the heel of your hand and see whether the latch moves. Run your hand along the pan slot on every level and find out whether your fist fits; if it does, the ferret's head does. Lift each shelf and look at the seam where it meets the frame. Then check the two corners of each panel, because that is where spacing is widest.
Anything you find is fixable with a carabiner, a cable tie or a strip of hardware cloth, and all three are cheaper than the afternoon you will spend looking behind a washing machine. Escape-proofing has the full checklist and the materials.
What this page does not claim
We have not tested a latch to failure, we have not had a ferret attempt any of these cages, and no body publishes a standard for small-animal cage hardware. The ranking is our assessment of published hardware descriptions and published bar spacing, with every figure attributed on the card and every gap in the documentation named rather than filled.
